Removing extra spaces in variable definition in configure script

With this commit, extra spaces in the definition of two variables in the
`configure' script have been removed. Since they are defined in a
`shell' context (not in `make'), variable assignation is not allow to
have any space at both sides of the `=' character. I detected these
typos when trying to run `./configure' in a particular project.
